STA El??? .application tiled. ctober 15,

To all 'wim/m, i may concern.'

Be it known that I, W ILLiAM J. lxnninn, Jr., a citizen of the United States, residing' at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Stamps, of which the following is a specifi-- ration.

My invention is an improvement in the class of stamps, similar to rubber stamps. and adapted to mark any suitable surfac with an imprint by' means of raised letters extending beyond a supporting base or surface.

The invention has in view to provide a stamp of this character, either`for hand use or mechanical application by rolls, in connection with a suitable inking pad or me dium.

One of the principal objects of the in vention is to provide a stamping element or die which may be attached to and used with a suitable supporting base, preferably resilient, whereby to avoid the necessity ot providing such hase for each particular stamp. Ordinarily, such stamps are made by molding the letters or characters in rubber on a printing portion which is permanently mounted and connected with the cushion, which in turn is affixed to the stamping handle or frame, the several parts forming inseparable portions of each stampingr unit. This practice, esi'iecially with stamps or rubber dies of large size, involves very .:onsiderable expense and storafgje room, which is avoided by my improvenient.

'lhe present invention comprises a supporting frame or holder having a resilient cushion portion, arranged in the are of a circle around its `under face and adapted to receive and hold, with suiiicient tension to maintain it in position, an operable weblike printing or stamping member, the trame having devices for stretching such member across the face of the cushion and fixedly holdingr it thereon, constructed and ipted to operate in the manner merc L,ly lnrcinat'ter ie.--.i'iilaal,

(S is a perspective detail view illustrating a portion of the printing and stamping# member, partly broken away. Fig. 7 is a view in side elevation illustrating the application of the invention to two supportingr rollers, arranged for double stamping. Fig. S an enlarged detail view, showing one of such rollers provided with adjusting devices for cari" end of the stamping member.

Referring to the hand operated machine, illustrated on sheet 1 of the drawings, it comprises a light portable frame of the desired size, preferably made of sheet metal having end portions 2, 2, connected by a berk 3 and a bottom portion 4. These arts arranged, as illustrated, for stincss convenience in use, and are provided h gripping handles 5, 5, one at each end, carried by the outwardly projecting brackets; 6, respectively. The bottom 4 eX- teuds around underneath from one of the end portions Q to the other in the are of a circle, of suitable radius to facilitate the rolling operation of the stamp, from one end to the othe, over the surface being marked. Upon the under side of the bottoni l is cemented, or otherwise suitably secured, a resilient pad or other suitable material, the outer surface of which is curved in parallelism with the base 4 and presents a smooth continuously curved supporting face for `the stamping elcnwnt from one end to the other.

.Sit e ch end the main frame is provided with a projecting ledge or flange S, 8,whieh may be conveniently made by extending the end in the manner shown, and redoubling it, as indicated at 9, for insuring strength and stiffness for the attaching and adjusting devices. y

The printing element consists of a strip l() of webbing. canvas, or other suitable material with nhich is incorporated the rubber nase il havin;r the projecting integral robber stamping characters 1Q., formed by molding. s; is vwell understood. The purpose el' inmaporating the web backing 10 with the rublar slrip il is to give the en tire stamping member sulicient strength/'so 7 of sponge cushion r that it. may be stretched taut over the curved eushion 7 without undue stretching, by thus reinforcing the rubber, and to also provide agains1 ordinary wear and tear. llaeh end of the stamping member 'for substantially the full width of the stamping` member at eaeh end, said terminal ieingry permanently eoi'ineeted with the stainpini;` member by molding it therewith, or otherwise eonneeting these parts in airv suitable way. In the ionstruetion shown, the .sheet metal terminal 13 is provided at its inner portion with a plurality of closely adjacent openings ift and intervening connecting portions 15, the rubber strip l1 being integrally toi-meti through the openings 14 and eaeli side of the sheet metal, as clearly illustrated in Fig. t3, by whieh means the parts are permanently eonneeted. lt will he understood, of Course, that the terminal 13 may be otherwise secured or attached, it desireth s' by ri veting or sewing, for the saine purpose.

The terminal lf3 is provided with a Series of longitudinal slots lti which extend outwardly tor snhstantially the Vfull width of the exposed portion of the terminal, and then innardly at right angles to its main body portion centi-ally through corresponding ii'iwardly bentl retaining lugs or Vlips 17, as indicated at 16.

Mounted transversely across the bottom 4 ot the frame at one or both ends is a tightening bar Yln the hand` machine, lY ordinarily utilize but one sueh tightening har,

due to the fact that the extent` of curvature ot the frame is not suicient to prevent ample tightening from one end only: At the tightening end ot' the frame, in suoli ease, l provide an adjusting screw 19, l), one for eaeh corner or side of the hase, extending through and rotatable in suitable openings in the reinforeed lint), each provided with a thumb terminal 20, 20. The bar i8 is eorrespondingly threaded, engaging; the serews I9. and said screws at their other ends: pass thro zip-turned lips or ligs 21, 21,forined ot the sheet metal of the bottom 4, hy punehing it nl'iwardly theret'roin, in the manner ..flearly illustrated in Figs. 3 and l.

The inner ends of belts l? are provided with a terminal hearing nut or eollzir with a tightening Set? nut, Cotter pin, or other suitable deviee. Th liar l is provided across 'its outer fare with a plurality' ot' pins 2f) and along' its outer edge with a correspondingF plurality ot' pins 9.1. The purpose of pins 23 is to facilitate the aline nient and adjustment. of the terminal 123 in applying it to the liar by engaging slots it?, and shits' iti; h l-'liiifg engxigeiizent with the lm and to retain the tei-.inutil i in r ld. in uilprovided with a metallic terminal i3, ot` thin sheet metal.1

ot' pine` Q4 to positively engage the 5 end.

i i l l l i i l l l l i i t l l l dition to the engagement with the bar itself by the right angle lips 1T.

The terminal 13 at the other end of the stamping member is ot the saine constructtien and. in the hand inaehine, is ordinarily hooked over the ijeint'oreed lip 9, which is also provided iiith a series of pins Q5, positively engaging' the slots 1G' and retaining that end ot' the stamping member.

For the purpose of facilitating the loperation of the adjustinb toni 4 is preferably made straight for a short portion of its length, as indicated at ft (see Figs. 4tand 5), thus providing a flat surface over whieh the har t8 may move in paralleli-:ui with the adjusting serews 19.

rThe hand grips .5 are preferably of the ednstruetion shown in the drawings, consisting ot eylindrieal-shaped handles rotatably mounted on eentralizing pins carried at each end in the bracket extension 6.

The operation of the invention will be readily understood from the foregoing description. When any particular stam-ping member is io be useiL it is merely slipped over the lipitv' and into eneagen'ient with pins Q5 at one end of the traine, laid across the eushion T, the other terminal l brought down o\er the bar with the slots registerine' a. ith the pins 2li and Ll. and the liar 18 is then tightened by the srrews until the printine element or st rip is' drawn tuut aero-s the eushion. The traine is then grasped by the handles 5, one in eaeii hand, and the printing; strip inked by :i 1partial rolling operation over a suitabte in tin;r pad, when the impression is; then nitide on the sin-tace to he marked, in the eaine manner.

The curved surface of the deviee zgreatly facilitates the markingr operation, enabling ample pressure to be exerted throughout the entire length of the stamp, insiringregularity ot' impresion and great speed.

`When it is desired tonse the. invention ii'i eonihiiiation with Supporting rollers` for the purpose of stamping two or more colors, two or more rollers 26 may be provided in the manner illustrated in Figs. 7 and ln suf-li ease the stainping elements or stripA are provided with letiers or charaeters whieh eo-aet to forni the entire stamped subjeet-matter, the rollers being s0 arranged that the .stamping portion of one will properly interlit and eornhine with that 0f the other. each reeeiving its proper amount of ink troni anni' .suitabhy source, as inking rollers 27, 27. ln f-ueh ease, the stamping strip 1l is triade in all respects substantially similar to that just described, except that it is provided at each end With adjusting sereiw 1Q. 19, misitively engaging adjustin.;r hars 18. 1P meh ot which effects a ,-itreteliinfr adyiustnient ot' the Strip at each Hiiih arrangement is preferable beeau-iotv` the laet that the plat-ing of the ing di strip around a suitable .portion of thel drum or wheel results in considerable additional friction, which is readily overcome by tightening from each end; In such arrangement the sarticle beingstamped, as a box 28, is fed along underneathy the rollers -upon any suitable surface 2-9, receiving an imprint from each roller successively, suitable feed mechanism, gearing, etc. to effect the proper operation of the machine being provided.

The advantages of my invention will be readily appreciated by all those familiar with this class of stamps. It facilitates the stamping operationg'it obviates the necessity of keeping on hand a large number of stamping bases, each having its particular stamp; it effects great economy in storage space of the several stamping elements; it is rapid and effective in changing the stamping strips; and, on account of the curved surface, it greatly simplifies and facilitates the use of tiie device by the workman.
